SPECIPICATIQN forming part of Letters Patent: No. 385,299, dated June26,1888.

Application filed August 20, 1887.

To all whom it may concern.-

Be it known that we, PETER A. COUPAL and Josnru COUPAL, of Boston, inthe county of Suffolk andState of Massachusetts, have invented certainnew and useful Improvements in Sewing-Machines for Connecting Soles andUppers, of which the following is a specification.

This invention relates to machines of the character shown in our pendingapplication for Letters Patent for scwing-nmchine for connecting solesand uppers, filed April 30, 1886, Serial No. 200,674 ;and it has foritsobjecttoprovide improved mechanism i'orsecuring uppers to soles ofturncd'shoes by stitches or loops of thread passed through the upper andthrough a portion of the sole and locked by tongues of leather cut inone of the sides of the sole, as shown in Letters Patent No. 242,328,granted to T. K. Keith, May 31, 188i.

Our invention consists in the combinations and improvements hereinafterdescribed and claimed, whereby the tongues of leather are cut, the loopsof thread are engaged therewith, the boot or shoe isfed after theengagement of each tongue and loop, and the shoe is supported during theoperation.

Of the accompanying drawings, forming a "part of thisspecification,Figures 1 and 2 represent side elevations of our improved nut chine.Fig. 3 represents a front elevation of the same. Figs. 4 to 22,inclusive, represent views of different parts of the machine, saidfigures being so referred to hereinafter as to render a separatedescription of them at this point superfluous. Figs. 23 to 30,inclusive, represent different parts of the operation of the machine.

.The same letters of reference indicate the same parts in all thefigures.

In the'drawings, a, represents the head or frame in which the drivingshaftb isjournaled, saidhead being supported by astandard or pedestal,0.. The driving-shaft is rotated by power applied to a driving-pulley,d, which is normally loose on said shaft and is connected thereto by aclutch operated by the depression of a treadle at the based thepedestal, the shaft being operativelyconnected with the Serial Np.247.445. (No model.)

driving-pulley so long as the treadlc is held depressed by the operatorand disconnected upon the release of the treadle. The clutch and meansfor operating it are old and well known in various types of machines,and as' theyform no part of our invention are not here particularlydescribed. To the drivingshaft are aflixed the series of cams which op-'crate the various parts of the machine, as

hereinafter described. i

causes the latter to oscillate the needle. relative arrangement and timeof operation of the knife-and needle are such that the needle movesforward after the knife has cut a tongue in the work and then recededtherefrom,f thc needle entering the cut made by the knife and andthrough the edge of the sole and the upper bearing against said edge, sothat the loop of thread drawn back by the needle through the upper andthe edge of the sole will be in' position to interlock with thetongue,as here'i nai'ter described. Y

. 0 represents a rest against which the upper. surface ofthe sole isheldby the operator during. the operation of the machine. Said rest we terma depth-gage, and its ofiice is to determine -the depth of the entranceof the feeding and'perforatingawl, hereinafter described, and the needleinto the sole.

' The depth gage is formed on aslide, w, which is adapted to move towardand from the front' of the machine in a fixed guide, and is normall'yvheld back by a spring, a. A lever,'b, Figs. 1 and 9, is provided,whereby the operator can move the depth-gage forward for the purpose ofplacing the upwardly-projecting edge a of the upper between said gageand the i'eeding-awl d. Said awl, which is an important part of ourinvention, is'aiiixed to an arm, e", which is adapted to reciprocatehorizontally in a slide or carrier, f, which in turn is adapted toreciprocate in fixed guides g g on the head a. The said block and slideare moved alternately to give the awl the following motions: first, aforward lengthwise motion to cause it to penetrate the work; secondly, aforward lateral-motion while it isengaged with the work, wherebythelatter isfed; thirdly, a backward lengthwise motion vto withdraw it fromthe work, after the feed movement, and,

fonrthly, a backward lateral motion'while itis' withdrawn from {thework, whereby it is returned to its startingpositi'on. 1 These motionsare efleeted bye-calm), a eanrgroove, 1'', both rotatedby'thedriving-sliaihj and a lever,]c', which is pivoted at l to ear's m, Fig.2, on a stud swiveled in a-iixed; bearing, a, sot-hat the lever canoscillate'in two planes atright ans gles to each other -viz.,on"theipi'vot-"li nd The lowerend of on the axis of the ears' n'z," thelever is. has a, slot, '0: ceivinga stud, p, on the blockzefiv-andothenslot, q-",Ireceiving a stud, 15', on the slide f'-,,= th'e slot 0'and studp being at .righ'tpangles'wit-h the slot q and stud-rflj rtecahi jf, acting on a roller, '3', on thelevcr kf ,f.g'ives' said leverthe movement whichicauses it to more; the slide f block c, and {awl'd inthcldire'ction required -to feed the work-,whilea spring, tfiiFig.8,.in-' terposcd between a part of the head a and anadjusting-screw,'uflori the. slidef', presses said slide in the opposite-directi-on, keeping the rollers" in-coiitactgwit-h' the cam'j andgiving the awl its backwardlateral movement.

The jaws w m are ailixeda espcctively,tole-. vers a'f b", which are bothpivoted at c" to a w, which is arranged to bear agai nstthe per.

tion of the upper that bears on the edge of the sole, and apenetrating-jaw or pointed dog, w,

arranged to penetrate the upper surface'of the sole between each tongueout by theknife and the point where-the next tongue is cut,the

dog being in advanceof the knife and outside or in front ofthedepth-gage, while thebaek gage is behind-the depth-gage and resiststhe thrust of the jaw :0 against the work. The

jaw or dog, by reason of its form and direction of movement, draws thesole upwardly against the depth-gage when it penetrates the fixed earonthe head a and have their upper ends connected by linked" d, Fig. 11, tothe lower end of aslidc, c, which is movable in a vertical guide in thehead a, and is reciprocated by a cam-groove, f",in the disk t on thedriving-shaft, said groove receiving a roller, g", on the slide e. Thelinks dd and levers a" b constitute a lazy-tongs operated by the upwardmovementof the slide a to move the jaws w 00' toward each ether andcause them a to grasp and hold the work,and by the downward movement ofsaid-slide to separate said jaws and relea'se the work.

In addition to the depth-gage wind jaws 'w' x as work-supportingdevices,- we'have .prov vided two automatically-adjusted rests, h i'arranged to bear on theside of the upper at diderent heights, the upperrest, h, being on der and close to the-awl, while the rest 1' is at alower point. i

The rest h" is a horizontal roller supported by a slide, j, adapted tomove horizontally in a guide or way on the head a and normally pressedforward bya spring, k", Figs. 2 and 13, which presses the rest outwardlytoward -lOO the operator and permits it to yield asnmy be required byvariations in the contour .of the UPDB The lower rest, t", is attachedto an arm, Zf,

which is pivoted at m! to an ear aflixed to the head a, and is adaptedto. oscillate, so as to give the rest i" a movement in the arc of acircle," whereby said rest is depressed when it is moved backward andraised as it is movedfor ward. This movement adapts the "rest 2' tosupport the thinner toe portion of the shoe, as shown .in Fig. 16, -aswell as the side porti'ons, as'shown in Fig. 15. The levcrl,.sup-

porting the rest i, is connectedby a link, 0'',

with a slide, p",fwhich is. parallel with the slide j, and, like thelatter, is adapted to slide horizontally in a guide or way, and ispressed forward by a spring, a", whereby the rest 1'" is normally heldin the position shownii n Figs. 1, 2,'and 13, and is permitted to morebackwardly and downwardly from said position, as shown in Figs. 15 and16.

An important part of our invention is the IIO provision'of means forautomatically locking the restsh i" in any position they may assume, andcausing them to act as rigid sup caused by the thread-pulling rotationof the tension wheel after the slack has been entirely taken up, theoperator pulling off the thread in preparing thejtnachine foropcrationto remove any thread on which the wax has dried orhardened.flhe sleeve 29 base flange, 3 5, faced with 'a-washer, 36, of feltorjother hie,

tional material, against which o'neside of the] tension-wheel bears.'The-gear 3 -t is connected tothe sleeve 29 by a key, 37, whlchcanses thesleeve and gear to rotate together. but permits the gear to movelengthwise of the sleeve. The gear is pressed by a'sprihg, 38, towardthe tension-wheel, and a frictional washer, 39, is interposed betweenthe gear and wheel. The-wheel is thus adapted to rotate independently ofthe gcar,a nd'while the spring-pressed,

gear and the frictional washers prevent such independent rotation duringthe regnlar'operation of the machine they permit; it when unusual strainis exerted on the thread, as by the operator pullingit from the wheel.

Operation: The'feed-awl being projected and the restsh" i nnlo'ckedandfree to yield, the

operator places the shoe'in position for. the

stitching operation, first movingthe depth gage outwardlyby means of.the lever b and keeping the bottom of the-sole against depthgage,pressing the shoeinwardlyagainst the aw], so that the latterpenetrates-theupper.

and the edge of the sole. The .awl is at this time about at the centerofits feeding movement from right to left, and upon-the starting of themachine the an] completes its feeding move-- ment, carrying the work tothe left and completing the feed movement. The jaws to a then approacheach other, the penetrating jaw w entering the outer surface of the solea'littie to the right'of the .awland pressing the work against thesupporting jaw to, and at the same time drawing thework upwardly againstthe depth gage. The worlds now held jointly by the jaws to a" and theawld. The rests h" i'are locked and made rigid by the describedlockingdevices just before the knife commences to cut and remain lockedduring the entire OpQlnhlOll of cutting the tongue,

drawing the loop ofthread through the work,

casting off the loop, and taking it up to interlock it with the tongue,said supports being released and made yielding only while the work isbeing fed. so that they conform to all the variations in-thecross-section of the lasted shoe while the latter is being fed, and areimmediatelylocked in each position they assume,

and therefore constitute a'firm supportfor the eaazee is enteri ngfthestock the loopcr swings down to bringthe thread under theneodle, and atthe same time the nwl, which has now entirely withdrawn fr onrthe' work,tnovcs laterally to" tance equal tot-he lengthof one stitch from theneedle. The heedle then moves back,

the upper and sole the cau'132-movesthe lever 30 and the tension-wheel28 in the direction in dictated by the arrows in Fig. 17, thus relievingthe thread of tension. The intermission of the tension thus effectedlasts until the barb of the needlehas drawn the thread through the work,and by relieving the strain on the needle during this part of its workgreatly diminishes the liability of breaking the thread.

After the barb of the needle has emerged with 4 the loop from the workthe tension-wheel is rotated in the opposite direction sufficientlytoexert a tension on the thread 'dnriug' tlie latter part of the operationof drawing out the loop. This tension tightens the thread on the outside'ofthe upperbetween the last stitch and the'onc being-formed? After theloop has heenyentirely drawn back the tension on' the thread isreleased.Whilethe needleis draw-- ing out the loop-the spreader is moved forwardunder the needle. When theloop is entirely drawn, the spreader is.depressed and bears upon the sole, the point of the spreaderbearing'onthe-root or base of the tongue last formed. This downwardmovement of the spreader causes the pinion 23 of the cast-olI bar tomove over vthe rack and be rotated by said rack, this movementswingingthe cast-off across the point of the needle and causing it drawing troor thread through the work. i

Whiletheneedle is drawi iig the thread through ICO to bear on the loop.J nst as the cast-oft" moves below the needle the latter moves slightlyforward to release the loop, which is then depressed and separated fromthe needle by the continued downward, ,movement ot' the casto-fi'. Afterthe casting off of the loop the tension wheel is rotated to tighten thestitch over the tongue, the loop spreader remaining on the tongue duringthis operation in position to cause thcloop to slip oil from its pointat the extreme base of the tongue, so that there is no possibility ofthe loop being laid 'suftlciently near the free end of the tongueto-make it liable to slip off from the tongue.

It will be observed that tension is exerted on the thread, first, totighten thatpart which lies atthe outside of the upper, and, secondly,

to tight-en the loop across-the tongue on the surface of the sole, sothat all parts of the loops or stitches are drawn tight and a. close'union between the upper and sole is effected. V

the, StitchI- interlockings otthe thread-loops with the tongues are atuniform distances t barb of the needle when-the latter is projectingports for the upper during the operation of cutting the tongues in thesole, and of drawing the loops of thread and interlocking them 8",formed on it.

with said tongues. The rests are thus looked just after the work is fedby the aw], and remain locked until just before the next feed movement,when they are unlocked and allowed to conform to the shape of theportion of the upper presented to them by the feed movement.

The mechanism employedfor locking and releasing the rests h t' may bevariously moditied. The mechanism here shown is as follows: Figs. 2, 13,and 14 represent a bolt, q", affixed to the head and located between theslides j" p, which carry the rests.

threaded portion is a nut, 1"", having an arm, Said arm is connected bya link, it, with one end of a lever, a, which is pivoted at v to thehead a, and has at its opposite end a roller which is held by a spring,

- w", Fig. 2, against a cam, v, on the drivingslides j" p" and theirrests, and when turned shaft, said-lever being oscillated by the cam andspring and turning the nut first in one direction and then in the otheronthe fixed bolt q". Between the nut r and the slides j" p" isinterposed a clamp, 3, made tubular at one end to bear against the innerend of the nutr", and provided at its other end with two clamping-faces,4 4, formed to bear against the outer surfaces of the slides j p. outersurfaces of the slides are preferably milled or corrugated, so that whenthe clamp is forced against the slides by the rotation of the nut itwill firmly lock said slides. It will be seen that when the nut r" isturned in one direction it will cause the clamp 3 to lock the in theopposite direction will release said slides. Aspring,s, may be employedto sepa-; rate the clamp from the slides when the nut releases theclamp.

5 represents the looper arm (best seen-in Fig. 17) which places thethread across the through the stock. Said arm is attached to thelooper-bar 6, which isjournaled in a hearing inthe head a, and isoscillated in said bearing by a sleeve, 7, which has a curved slot, 8,Fig. 20, receiving a stud on said bar.v Said sleeve is reciprocatcdonthe looper-bar bya lever, 9, Fig. 17, pivotedat 10 to the head a, andconnected at one end to the sleeve 7 and at the other 'end to theawl-carrying ba're. The movcmentsof said bar oscillate the lever handcause the latter to reciprocate the sleeve 7, the slot of which, actingon the stud ofthe looperbur, rocks the latter at the proper times.

12 represents .the loop-spreader, which enters the loop drawn out by theneedle preparatory to the operation of casting oil the loop from theneedle. Said loop spreader is a curved arm rigidly attached to a slide,13,

which is adapted to move in a guide-lever,14.

Said lever is pivoted at 15 to a fixed car on The belt is screw-Qthreaded at its outer portion, and on said Said faces and the cillatetheloop spreader toward and from the work. The loop-spreader has also anupwardand-downward movement imparted by a slide,

18, adapted to move vertically in a guide in the head a, a cam-groove,19, Fig. 22, receiving a roll on the slide 18, and a link, 20,connecting the slide 18 with the loop-spreadercarrying slide 13.

The cast-01f 21 is a bent-wire arm attached to a rock-shaft, 22, whichis journaled in bearings on the side of the spreader 12, and has on itsupper end a pinion, 23,\vhich meshes with a rack, 24.' Said rack isfitted to'slide in a guide, 25, attached to the loop-spreader 12, and isconnected by a link, 26, with a fixed ear,27,on thehcad a. The upwardanddownward movementsof the loop-spreader cause the rack 24, which doesnot move up anddown, to rotate or rock the pinion 23 and thus oscillatethe cast-ofi.

The successive movements of the loopspreader and castoft' are asfollows: During the latter part of the outward or backward movement ofthe needle the loop-spreader is swung forward under the needle, as shownin Fig; 26, and then is somewhat depressed, as shown in Fig. 27, by thedownward movement of the slide 13. is moved slightly forward to releasethe loop, and then the'cast-oti' is swung downwardly upon the releasedloop and presses it-downwardly from the needle, as, shown in Fig. 28.

At the same time theueedle' The point of the spreader now standsdirectly over the/tongue on the sole,and whileit stands in this positionthe take-up draws in the loop, which is caused by the point of thespreader to tighten over the base of the tongue, Fig. 29. The spreaderthen swings back out of the way before the next forward movement of theknife.

28 represents a grooved tension wheel,whieh is adapted to rotate on asleeve, 29,- Fig. 18, which is mounted on a stud affixed to the head.Said wheel is rotated-alternately in opposite directions by means of alever, 30,- pivoted at 31 to a fixed car on the h'eada, a cam-groove,32, in a disk on the driving-shaft, said groove receiving a roller onone end of said lever and site end of the lever '30, and a gear, 34,connected with the tension-wheel and meshing with said rack. The cam istimed to oscillate the lever 30 and cause the rackand gear to rotale thetension wheel to loosen the thread while it, is being drawn through thematerial by the needle and tighten it to take up the stitches, ashereinafter explained.

The tension-wheel is adapted to rotate independently of the gear, and isconncctedthere with by friction devices, which, while causing the wheelto rotate with the gear in theoperation of the machine, when the threadis not under unusual strain; permits it to be indepeudently rotated bystrain on the thread jection is obviated by our iinpro-vcd outside feed,

The depth gage is arranged to support the upper surface of the soledirectly over the point where the awl cnters thesole preparatory tofeeding it. The lateral extension of said gage enables it to firmlysupport the shoe and prevent it from tipping lengthwise, so

' that each awl-holc is made at a uniform depth.

The capability of the depthgage to move outwardly enables the projectingedge of the upper to be rcadily'placed behind the depthgage inpresenting the shoe to the machine.

The movement of the aw] effected by the spring i, whereby the awl iscarried backwardl'y preparatory to entering the shoe to feed the same,is arrested by a wedge, 40, affixed to a slide, 41, which is verticallymovable in guides in the head a. Said wedge is connected by a rod, 42,with a treadle, (notshown,) whereby it may be depressed to arrest thedescribedmovement of the am at any desired point, and thereby regulatethe length of the stitches or the distance between the tongues.
